SPRING-SADDLE.

Specification of Letters Patent.

Patented June 13, 1am.

Application filed December 8, 1914. Serial No. 876,044.

To all whom it may concern:

Be it known that I, CHARLES A. PERSONS, a citizen of the United States, residing at Worcester, in the county of Worcester, State of Massachusetts, have invented a certain new and useful Improvement in Spring- Saddles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to seats or saddles but more particularly to such as are adapted for use on velocipedes, bicycles, motorcycles and the like and has for its object to provide a structure which is more simple and efiicient in operation than any device of a similar nature heretofore known.

It has heretofore been common practice to make a form of cantle supporting spring in which the compression and extension springs forming the same are placed sub-' stantially end to end so that they had the appearance of being all in one part, and the compression spring was quite generally made in a conical form for neatness in appearance and freedom of action, though this was not essential. The extension spring was generally suspended from the supporting frame or truss by its upper extremity in the manner common to compound spring supports and the lower extremity of the compression spring was secured to the same bolt as the upper extremity of the corresponding extension spring by an eyelet looping such bolt. lVithin these two springs and substantially coaxial therewith passes a depending rod having its upper extremity secured to the under side of the seat and its lower extremity connected to the corresponding lower extremity of the extension spring. The upper extremity of the compression spring coacts with a shoulder on such rod so that a depression of the rod due to a shock compresses the compression spring and extends the extension spring simultaneously. This spring is so constructed that no adj ustment is possibleby the rider. I

In order to provide a spring support of the type described, but which is capable of easy adjustment to suit the different riders, a form of spring supportand means for attaching the same to the seat supporting frame or truss has been devised inwhich the spring action may be readily adjusted at anytime.

Referring to the drawings :Figure 1 is a rear elevation of a saddle complete in which one of the cantle supports is in section and .the other is shown in full, as will be fully described hereinafter. Fig. 2, central vertical section of a modified form of the invention, as will be fully described hereinafter.

In the drawings the embodiment shown in Fig. 1 comprises a seat '10 mounted on a supporting frame here composed of trusses 12 and 13, respectively composed of the upper wires 14 and 15 and the lower wires 16 and 17. As these two trusses or frames are substantially the same except thattheir parts are reversed and as the particular type forms no part of the present invention, no detailed description of the same'will be given here as their construction is well known in the art and any form of truss or frame may extremities with clamping heads 20 and 21 respectively adapted to grip two adjacent coils of the compression springs 22 and 23 respectively in the manner shown in Fig. 1.

In the embodiment shown in Fig.1 the compression springs 22 and 23 and their respective extension springs. 24. and '25 are formed integral by merely varying the winding in the two portions of the spring. As the springs on each side of the cantle are the same, only that composedof the compressible portion 22 and the extensible portion 24 will be described as such description will apply equally to the spring composed of the compressible portion 23 and the extensible portion 25.

For brevity of description the compound spring composed of the portions 22 and 24.- will be hereinafterreferred to as the sprlng 26. The lower extremity 27 of this spring 26 is here formed into an eyelet and clamped to the lower extremity of the depending rod 100 the compression portion 22 coacts with a shoulder 29here' formed on the rod 28 which extends upwardly within the coils of the spring 26 preferably substantially coaxial therewith.

In the embodiment of the invention shown in Fig. 1 of the drawings, the two lowest coils of the compressionportion 22 of the spring-26 have been engaged by the clamp ing head 20 of the bolt 18, but: this may be readily adjusted by loosening the binding 7 nut 30 on such bolt and turning the spring 7 within the head until the head grips the next two coils above those shown engaged, or, in fact any two adjacent coils that maybe desired, and thus-the number of coils acting as a compression spring will be varied, for all those below the bolt 18, which fastens the spring to truss, will act as extension spring coils, even though they have been wound in the manner usual for a compression spring. To. move the binding post or bolt 18 upwardlyrelative' to the spring tends to stiffen the compression element and correspondingly render more yielding the extension element; By so adjustingthe relative resist-' ance of the compression and extension element, the r der can secure the sprlng action which produces the greatest comfort for his particular weight, aside from many other advantages which will be readily evident to one skilled in the art. j V

In the embodiment shown in Fig. 2, the extensible andcompressible elements 31 and 32 respectively of the cantle supporting springs are separate springs instead of being formed integral in the manner previously described for the embodiment of Fig.

1 and the extensible elementhas its upper extremity formed into an eyelet 33 Which fits about the bolt 34, corresponding to the bolt 18 in the previous embodiment, and is provided with a" clamping head This bolt 34 engages the rear extremity of the truss inthe same manner as was described in connection with Fig. ,1 and this head 35 engages the two next adjacent coils of the 'fourthinstead of the-first and'seco'nd coils as shown "the drawings, 5 the lower extremity of the compressible element will rest within-and be enveloped by the upper. coils of the extensible element. Thus the same adcompressible spring 32. The compressible spring is preferably of different coil diameter than'tha't of the extensible spring so that "they may telescope. In the particular embodiment shown in Fig. 2, the'compres-v sible element is of smaller diameter than the extensible'element so that when the clampingpost or bolt 34 is moved upwardly to 'en- 1 gage the second 'and third *orthird and justability is obtained as with; the embodi mentshown in Fig. 1 of the drawing; a V

The applicant is aware that numerous changes in the arrangement and construction 'of'parts may readily be made by any one skilled in the art without departing from the scope of his invention and he does not care to be limited to the particular embodiments herein shown and described.
